What is JTAG and how can I make use of it? - XJTAG Tutorial

The debug and programming tools commonly associated with JTAG only make use of one aspect of the underlying technology — the four-wire JTAG communications protocol. This standard was developed to provide a technology for testing Printed Circuit Board Assemblies PCBAs without needing the level of physical access required for bed-of-nails testing or the amount of custom development needed for functional test. The TAP was designed to interact with new registers that were added to devices jtag apps and themes implement this method of testing.

Very quickly however silicon manufacturers recognised the benefits of using the TAP to access registers offering other functionalities such as debug and programming. As its name suggests the individual bits, or cells, of this register are at the boundary of the device, between its functional core and the pins or balls by which it is connected to a board — very often JTAG testing is referred to as boundary scan.

In their functional mode they have no effect on the operation of the device — this is the mode in which they operate when the board is running normally. In their jtag apps and themes mode they disconnect the functional core of the device from the pins. By putting boundary scan cells into test mode they can be used to control the values being driven from an enabled device onto a net and also be used to monitor the value jtag apps and themes that net.

Disconnecting the control of the pins from the functionality of the enabled device makes boundary scan test development significantly easier than traditional functional test as no device configuration or booting is required to use the pins, jtag apps and themes. By providing a mechanism to control and monitor all the enabled signals on a device from a four-pin TAP, JTAG significantly reduces the physical access required to test a board.

There are two main ways that this boundary scan capability can be used to test a board. The first way, jtag apps and themes, connection testing see next section gives good test coverage, particularly for short circuit faults. What is a JTAG connection test? Where two JTAG enabled pins are meant to be connected the test will make sure one pin can be controlled by the other. Where enabled pins are not meant to be connected they are tested for short circuit faults by driving one pin and checking that these values are not read on the other pins.

XJTAG will automatically generate the vectors required to run a connection test based on the netlist of a board and JTAG information for the enabled devices. What about devices that are not JTAG enabled? In order to add this open circuit coverage it is necessary to communicate with the peripheral device from boundary scan on the enabled device, jtag apps and themes. If communication can be verified, there cannot be an open circuit fault.

This type of testing can be very simple, for example lighting an LED and asking an operator to verify it has activated, or more complex, for example writing data into the memory array of a RAM and reading it back. Is it a lot of work to create a JTAG test system?
